Life-history theory suggests that animals may skip reproductive events after initial maturation to maximize lifetime fitness. In iteroparous teleosts, verifying past spawning history is particularly difficult; the degree of skipped at population level therefore remains unknown. We unequivocally show frequent in Northeast Arctic cod (NEAC) a massive field and laboratory effort from 2006 2008. This was verified by postovulatory follicles temporarily arrested ovaries close putative period. At...

Throughout their range, spp. are adapted to a diversity ecological niches, overlapping spatial...
The contents of total arsenic and inorganic were determined in fillet samples Northeast Artic cod, herring, mackerel, Greenland halibut, tusk, saithe Atlantic halibut. In total, 923 individual fish analysed. mostly caught the open sea off coast Norway, from 40 positions. determination was carried out by inductively coupled plasma mass spectrometry following microwave-assisted wet digestion. high-performance liquid chromatography–ICP-MS dissolution samples. concentrations found for varied...
The redfishes (genus Sebastes ) are long-lived, commercial species in the North Atlantic. Excessive harvest through decades has led to a decline mature population of golden redfish ( norvegicus Norwegian waters, which is currently considered severely depleted. Accumulating genetic evidence suggests more complex structure within this genus Atlantic, recently inspired hypotheses cryptic S. norvegicus. Despite apparent divergence between two types, they have yet be verified morphologically....
The present paper presents the practical implementation of Ecosystem Approach to Fisheries Management (EAFM) in Norway. This involves defining management objectives and developing simple efficient tools achieve an overview needs prioritise among these, while integrating broader conservation issues ensuring stakeholder involvement. A new Marine Resources Act entered into force Norway 2009. By sustainable use as basic principles, law represents a paradigm shift Norwegian fisheries. indicates...
In this contribution, we propose fishery driven predator release as the cause for largest grazing event ever observed in NE Atlantic. Based on evolving appreciation of limits to population connectivity, published and previously unpublished data, discuss whether overfishing caused a grazer bloom sea urchin (Strongylocentrotus droebachiensis) resulting overgrazing more than 2000 km2 kelp (Laminaria hyperborea) forest along Norwegian Russian coasts during 1970 s. We show that coastal fisheries...
Abstract Impacts of climate change on ocean productivity sustaining world fisheries are predominantly negative but vary greatly among regions. We assessed how 39 resources—ranging from data‐poor to data‐rich stocks—in the North East Atlantic most likely affected under intermediate emission scenario RCP4.5 towards 2050. This region is one productive waters in subjected pronounced change, especially northernmost part. In this impact assessment, we applied a hybrid solution combining expert...

Probability-based surveying using self-sampling to estimate catch effort in Norway's coastal tourist fishery. – ICES Journal of Marine Science, 68: 1785–1791. Recreational fishing as a activity has become an increasingly important part the Norwegian travel industry may contribute significantly mortality on cod (Gadus morhua). Quantifying catches fishery is...
Beaked redfish inhabits North Atlantic waters in the depth range 100–950 m, over continental shelf, slope and open ocean. Individuals can live demersal or pelagic, at various stages of their life cycle. The geographical distribution species extends to most from Newfoundland Labrador basin west Barents Sea east. Monitoring beaked is challenging because wide large scale migrations; deep distribution, which complicates trawling hydroacoustic surveys; difficulties with tagging; persistent...
Abstract Recreational fishing (RF) is a large yet undervalued component of fisheries globally. While progress has been made in monitoring, assessing, and managing the sector isolation, integration RF into management multi‐sector limited, particularly relative to commercial sector. This marginalises recreational fishers reduces likelihood achieving sector's objectives and, more broadly, sustainability. We examined nature extent inclusion harvest strategies (HSs) for marine across 15 regions...
Abstract Greenland halibut (Reinhardtius hippoglossoides (Walbaum)) are widely distributed over extensive geographic areas of both the Northwest and Northeast Atlantic Ocean with no break in continuity respective distributions. Although entire resource North is genetically homogeneous they mainly comprise a single interbreeding stock each two regional investigated. Both stocks show similar distribution patterns depth. Generally, larger fish become more abundant smaller less progressively...
Abstract With the decline of many world’s fisheries, increased regulation, including marine protected areas (MPA), forms an increasingly important role in promoting sustainable resource use. Here, we present a novel “real-time” genetic monitoring programme used to protect depleted Norwegian coastal cod stock (NCC) MPA during spawning season, while fishery targeted at Northeast Arctic (NEAC) operates immediately outside. In period 2009–2016, >6800 from were genotyped with PanI locus...
With diminishing seabird populations and little knowledge on incidental bycatch in fisheries the Northeast Atlantic, this study aimed to screen Norwegian coastal 2009. The purpose was 1) quantify magnitude of rates estimate total from entire fleet by different estimators 2) evaluate data an access point survey against monitoring a reference as methods for collecting mortality seabirds 3) give advice further studies. focused three small-vessel (<15 m LOA) outside Northern Norway; cod (gillnet...
Identifying how physical and biotic factors shape genetic connectivity among populations in time space is essential to our understanding of the evolutionary trajectory as well management marine species. Atlantic cod a widespread commercially important species displaying several ecotypes with different life history strategies. Using three sets SNPs: neutral, informative, genome-inversion linked, we studied population structure ~2500 coastal (CC) from 40 locations along Norway's 2500 km...
Abstract Stefánsson, M. Ö., Reinert, J., Sigurðsson, Þ., Kristinsson, K., Nedreaas, and Pampoulie, C. 2009. Depth as a potential driver of genetic structure Sebastes mentella across the North Atlantic Ocean. – ICES Journal Marine Science, 66: 680–690. A primary question that remains to be answered about fishery for is whether it exploits several stocks within To address this issue, 1240 redfish were collected from fishing grounds in late 2006 early 2007 genotyped at 12 microsatellite loci....
